From another source:

Backpropagation Through Time (BPTT) is an adaptation of backpropagation used for training recurrent neural networks (RNNs), which are designed to process sequences of data and have internal memory. Because the output at a given time step might depend on inputs from previous time steps, the forward pass involves unfolding the RNN through time, which essentially converts it into a deep feedforward neural network with shared weights across the time steps. The error for each time step is computed, and then BPTT is used to calculate the gradients across the entire unfolded sequence, propagating the error not just backward through the layers but also backward through the time steps. Updates are then made to the network weights in a way that should minimize errors for all time steps. This is computationally more involved than standard backpropagation and has its own challenges such as exploding or vanishing gradients"

It's not really an issue they were just extremely cautious, something you'd expect in South Africa if you know anything about their power grid. I believe the author was actually trying to show it is actually feasible and range is not a concern.

Someone please correct me if I'm wrong or my terminology is wrong.

As the saying goes, it happens slowly and then all at once.

I would hope people exercise to a limited extent anyway, to the extent their bodies will try retain a baseline level of muscle-stength needed day to day.

As you've read on my other comment, I lost 20kg over 6 months on a low carb, low sugar, higher protein diet. I started gyming about 4/5 months in and I personally attribute this gyming with a chain-reaction that led to me putting the weight back on and am now in a much worse position health wise, even muscle wise. This all due to practical reasons, such as increased appetite which upset the hard-fought dietary and hunger equilibrium I reached.

Exercising too is I'm sure definitely better but I feel is way more difficult and sets many, on the weightloss journey, up to fail.

I actually lost 20kg over 6 month, roughly following this advice. Not strictly, like I would be more lenient on weekends with carbs & booze, and have sugar, like a small dark chocolate, but only at night (to avoid further craving and consumption the whole day). I avoided the exercise as it made me unbearably hungry.

I recommend this 100%
